APPARATUS FOR DRYING TILE.

SPECIFICATION forming part of Letters Patent No. 751,852, dated February9, 1904.

Application filed April 28, 1903. Serial No. 154,648. (No model.)

To all whom it may concern,.-

Be it known that I, DAVTD FORD HENRY, Jr. a citizen of the UnitedStates, residing at Port Murry, in the county of vWarren and State ofNew Jersey, have invented certain new and useful Improvements inApparatus for Drying Fireprooiing-T ile, &c. of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to the drying of clay and other wares preparatoryto burning, and has particular reference to improved apparatus foreecting a rapid, economic, and thorough drying of freproofing-tile.

r1`he invention consists in the novel structural features andarrangement of parts hereinafter fully described and claimed, andillustrated by the accompanying drawings, where- Figure 1 is averticallongitudinal sectional View of apparatus constructed in accordance withmy invention. Fig. 2 is a top plan View of the same, partly in section.Fig. 3 is a front elevation. Fig. 4 is a sectional elevation of thedischarging end of the apparatus, taken on line 4 4 of Fig. 2. Fig. 5 isa plan view of the air-inlet mechanism shown in Fig. 4. Figs. 6 and 7are detail views of the pallet hangers or carriers. Fig. 8 is asimilarrview of the pallet.

Referring to the drawings, 2 designates the drying chamber or tunnelhaving ware-inlet opening 3 at the upper end of front end wall 4, andrising from said end is stack 5, while at the bottom of the chamber andnear its discharge end is air-inlet 6. Extending from the ioor nearly tothe crown of the chamber are baile walls or mantels 7, and alternatingtherewith are similar walls or mantels 8, depending from thechamber-crown nearly to the iioor. thus formed which communicatealternately at the top and bottom, thus providing a circuitous orindirect passage for the ware, also for the air.

At the outlet end of the drier is compartment 9', and beneath the latterand open thereto at 10 is chamber or passage 11, which eX- tends to thefront of the drier, where it is open in front of end wall 4.

A succession of compartments is` Extending across the drier adjacent itstop and bottom are shafts 12, carrying sprocketwheels 13, and passingover and around the sprockets are the endless conveyer-chains 14, whichreturn from the discharge to the inlet end of the apparatus throughchamber 11, sprockets being provided therefor at the ends of saidchamber, with horizontal guideways or slides 16 between the sprockets tosustain the chains and prevent sagging.

17 represents hangers pivoted in pairs at 18 to the inner sides ofchains 14, with inwardlydisposed lifts 19, hinged at 20 to the lowerends thereof and adapted to turn upward thereon, the arrangement beingsuch as to prevent the lifts from dropping below horil zontal position.

At the front or inlet end of the drier and in the path of the conveyeris table or support 21, adapted to receive the ware-carrying pallets 22and sustain them in position between chains 14, to be engaged at theends and carried upward and forward by lifts 19 and hangers 18. Thepallets are formed, preferably, of perforated sheet or plate metalstrengthened by turning the edges thereof, as shown at 22.

l/Vith the hangers loosely pivoted between the chains'the pallets, ifproperly loaded, will remain in upright position throughout the entirecourse, passing upward and downward around the sprocket shafts andwheels and around mantels 7 and 8 until they finally emerge into theupper portion of compart- -ment 9. In this compartment the chains andhangers descend on opposite sides of car or truck 23 and automaticallydeposit thereon the pallets of dried tile, the chains and hangersdescending therefrom through openings 10 into return-passage 11. Thepallets may be Adeposited on the car in courses three or more partment9, intercepted by turn-table 26, the 100 empty cars may enter and theloaded cars emerge from either the end or side of the structure, as maybe most convenient in passing to and from the kilns.

For actuating the conveyer a shaft 27 is supported on the exterior ofthe drier on brackets 28 and operatively connected to upper shafts l2 byworm-gearing 29.

Stack 5 is arranged at the ware-inlet end of the drier, and air-inlet 6adjacent the waredischarging end, so that the conveyer and aircurrentsmove in reverse directions, thereby effecting a rapid and thoroughdrying of the ware. The dried tile approaching the discharge end of theAdrier are enveloped by the dry inilowing air, and as the latter iiowsforward toward stack 5 and becomes laden with moisture absorbed from thetile it comes in contact only with the greener tile in preliminarystages of drying.

Air may be supplied to inlet 6 by any suitable means, that here shownbeing a blower 30, arranged to draw its supply from a conduit 3l,leading to kilns (not shown) in which the ware is burned, thus utilizingheat from burned or burning kilns which is usually wasted. When heatedair from kilns is not available, the blower may draw its supply from theatmosphere through inlet 32, the double-acting valve or damper 33serving to simultaneously open inlet 82 and to close the kiln-passage,and vice versa. Before entering the blower the air may be drawn througha nest of steam coils or pipes 34E, and thus heated, the same beingdesigned more especially fil use where hot air from kilns is not availae.

It will be understood that the number of mantels or baffle-walls may beincreased or diminished as required and that the distance betweenadjacent hangers or pallet-carriers may be varied. Manifestly theapparatus may be variously embodied as regards structural detailswithout departing from the spirit and scope of the invention.

I claim as my inventionl. In drying apparatus, a drying-chamber, asuccession of/open vertical partitions forming a circuitous conveyercourse therein, and a conveyer movable through said course.

2. In drying apparatus, a drying-chamber, a succession of :open verticalpartitions therein forming a circuitous conveyer course, a
